ivmonrnn'ron LINING on Manama UP BOOK covnns;

Application filed September 23, 1925, Serial No. 58,214, and in GreatBritainAugust 5, 1925.

This invention relates to machines for forming the blind or other linessuch as gold and ink lines on the rounded ba'ck'of books ofmiscellaneous sizes and thicknesses in which all the lines are formed inone operation (herein referred to as lining for convenience) The objectof this invention is to provide a machine which will effect the liningin a better manner than heretofore, in that )IGSSUIB exerted bytlie'lining tools is mannally applied and can therefore be suited to thework.

Other features consist in arranging that the book is held stationary; inproviding lining'tools inthe form of discs and mounting these so thatthey are non rotatable when blind lines are desired, whereby it is foundthat a glossy or burnished effect is'obtained, and rotatably mountingthem when gold or ink lines are desired; and in mounting and operatingthe tools by'a lever frame and providing said lever with a number ofhandles situated at diiferent distances from the fulcrum so that theeffective force applied tomove the tools can be varied as required Asetting gauge'is also provided for correctly. aligning the book andtools in relation to each other;

Referring to the drawings Fig. 1 is a perspective view of a liningmachine.

Fig. 2 is a longitudinal sectional elevation.

Fig. 3 is in transverse sectional elevation.

Fig. 1 is an elevation of means for inking the tools.

In the particular construction illustrated which will now be describedas an example of a machine according to this invention, the apparatuscomprises a rectangular boxlike main frame 1, having two clampingmembers 2 3 adapted to receive and hold the book 4; at least one ofwhich clamping members is movable, preferably under the control of ascrew 5 operated from a hand wheel 6 on the exterior of the main frame.A setting gauge 7 is provided, and is dis posed between the clampingmembers adapted to position the book in relation to the tools.

, Y On the top of the frame 1 at one'end frame extends from one side ofthe pivot across the top of the main frame and is free at its other end11.

Slidably mounted on the guide frame is a carriage 12 having downwardlyextending lugs 13'Wl110l1 project into the main frame and carry aspindle 14 on which is mounted aseries of discs 15 forming the liningtools. For blind lines as in the construction illustrated the spindleand discs are fixed by the grub screws 16 (see Fig. 4) so that they donot rotate, for the purpose alread T described, but for gold orinklining Work they are arranged that the discs rotate.

The carriage has a pin and slot connection at each side thereof with alever-like frame, the carriage being preferably provided with projectingpins 17 which engage in slots 18 in the frame. This lever frame consistsof two bars 19 one at each side of the main frame pivotally mounted at20. These bars extend upwardly and are provided with a number ofransverse rods 21, 22, 23'clisposed at different distances from thefulcrum and constituting handles any one of which can be selected bythe'operator so as to vary the leverage.

The carriage with'the lining tools is so arranged that it is rocked onthe guide frame and thereby moved from on'efside to the other of theclamping members under the action of the lever frame. When the tools areidle, such as when a book is being placed into the clamping members,preparatory to lining. the tools will lie at one side of the clampingmembers. In a position, therefore, directly beneath this idle positionof the discs a. series of gas burners 25 or other suitable heatingdevices are disposed so as to heat the tool; it being understood that inthe case of gold and ink lining this burner is replaced by appropriatemeans for applying the ink or gold thereto.

In order to regulate the pressure of the lining tools as they move overthe book, the free end 11 of the guide frame can be pressed down to therequired extent; this end being normally supported by a transverse framemember 26, which is cut away at 27 on one side so that it can beconveniently grasped by the operator to enable him thereby to press downthe guide frame.

lVhere ink lining is to be performed a device such as shown in Fig. lwill be provided for inking the discs automatically and such device maycomprise an inking roller ll ll l JU 30 mounted by the slides 31 in theslot 32 ot' the bracket 33 and arranged with a spring 3% adapted topress the inking roller downwardly to bear upon the periphery of thediscs. An inl: container 35 is provided mving a roller 36 therein and aninter mediate roller 37 adapted to receive ink from the roller in thecontainer and supply it to the inking roller. This inking device is-arried by a bracket 38 so to move with the discs.

This apparatus is simple and cheap to produce and is advantageous inthat the book is held quite rigid and the pressure on the tools can beadjusted to any desired extent. giving an even lining.

Having now fully described my invention what I claim and desire tosecure by Letters Patent is l. A machine for the purpose specifiedcoi'i'iprising in combination, means for holding the book, lining tools.means for reciprocating the lining tools, and means pivotally mounted atone end and extending across the machine above said book holding meansand being manually operable at its free end for moving the lining toolstowards the hook durin reciprocation of the said tools so that thepressure exerted on the lining tools can be suited to the work.

2. A machine for the purpose specilied comprising in combination,stationary means for holding the book. lining tools mounted toreciprocate above said hook holding means from a position on one side toa position at the other side thereof. and a stationary heating devicedisposed at one side of the book holding means in a position beneath thelining tools when these are in their terminal the pos tion at thcorresponding side 0-." look holding means so arranged that the heatedwhile they are idle and are maintained in a heated condition ready forimmediate use.

A machine for the purpose specified comprising in combination. a clamptor receiving and holding the book in a llXQtl position, lining tools, amanually operable frame pivoted at one side of the machine. extending"across the machine above said clamp. and mov ble towards or awaytherefrom so that the pressure 01 the lining tools can be suited to thework. means for rcciprocably iii-taunting said lining tools on saidframe and means for moving said tools: on said tran'ie.

l-. A machine for the purpose specified con'iprising in combination. aclamp for receiving and holding the book in a fined position. liningtools. a manually operable frame pivoted at one side of the nnu-hine.extending across the machine above said clamp, and n'iovable tOVHl'L'tlSor away therefrom so that the pressure of the lining tools can be suitedto the work. means for reciprocably mounting" said lining toills on saidframe. a manually operable lever-like member pivoted at its lower end tothe machine and extending: upwardly. means operably connecting saidlevers to said means tor mounting" the tools and a number of handlesdisposed in spaced positions on the upper part oi said level-dikemembers any one of which can be selected so as to vary the leverage ofthe said member.

in testimony whereot I attix my signature.
